What is it?
 

2019 370Z. I'm putting 25mm wheel spacers on. Did the rear first an am pleased. I went to do the front, and sticking out from between the lug bolts is a little gobthrob that prevents the new wheel spacer from going on. It is about the dia and length of a tire stem, but is sleeved and capped with a 10mm hexhead bolt. This is passenger side front. I stopped there so don't know whats on the driver side front.
I'll go ahead and mention this too. The rear wheel mounts (that the name?) had a gobthroob in the form of a flush disc, about the size of a quarter; it had a partial slot in it - like a screwdriver at an angle had jabbed it.
So, what do I have here, and how do I deal with it?

It's an indexing/aligning pin for the stock wheels. You can remove it.

Thanx, Ark. My biggest fear was if I opened it, all the blinker oil would spill out. :icon17:
